Product Description:
Surface sizing agent is a new type of surface sizing agent that synthesized by copolymerization of styrene and ester. It can efficiently combine with starch result with good cross link intensity and hydrophobic properties. With lower dosage, lower cost and easy use advantages, it has good film-forming and strengthening property to writing paper, copy paper and other fine papers. Alkyl Ketene Dimer ( AKD Wax ), Cationic Reagent (3-Chloro-2-Hydroxypropyltrimethyl Ammonium Chloride/quat 188/CHPTAC), general AKD Emulsifier 25%, Quat 188 69%,Polymer emulsifier 40%, PolyDADMAC 40%,Wet strenght agent 12.5%/25%, Styrene Acrylic Copolymer, Fixing Agent 50%, Poly Aluminium Chloride, Sodium Gluconate Oxidized Starch,ect.
Functions:
1.It can significantly improve the surface strength.
2.Partly replace the usage of internal sizing agent.
3.It also has good mechanical stability with less bubbles generated during the operational process.
